一种用于负载自动化中非中性线交流开关的简单迟滞能量收集方法

This paper presents a simple hysteretic method to obtain the energy required to operate the gate-drive, sensors, and other circuits within nonneutral ac switches intended for use in load automated buildings. The proposed method features a switch-mode low part-count self-powered mosfet ac switch that achieves efficiency and load current THD figures comparable to those of an externally gate-driven s...
